our report from our chief science correspondent, robert bazell. >> reporter: for the first time ever, an experimental drug is showing great promise of slowing the alzheimer's disease. >> this is the first time we are seeing a slowing of the cognitive decline in patients with alzheimer's disease in this type of drug treatment. >> reporter: at first, the experimental drug seemed to fail as has every experimental drug to date. but when the manufacturer looked at it more closely, it found those with more mild disease had a less memory loss than those with the placebo, the 71-year-old retired expert still functions well. >> there are things that take a lot longer than they used to because i keep forgetting the order in which things have to be done. >> reporter: the results presented today combined studies with a total of 2,000 patients in the last two months. most scientists say it wouldn't be enough to reach the fda approval. but further studies show that it could help people with early alzheimer's disease. the drug is certainly not the cure that everybody wants, but for al krieger and mi

one of the coolest science kits in a longtime. building the circuitry to make the speakers, and you have two different cases to put your mp-3 player in, and then it's playing some music. it's actually the leapfrog that's making some noise, but it's -- the box from the laws of physics actually make it louder which is really cool. >> cool. >> now another example -- enough music. >> thank you, al. >> another lesson in circuits from laser pegs. love these sets. about $20, making them more accessible. build the models to their specs or open-ended for kids with special needs. >> jigsaw puzzles. >> one of the best uses of apps. some did not fare well but this one really works. ravens burger puzzle. build this 1,000-piece puzzle. this is something you'll want to do together, and look what happens. when he -- when he puts the ipad on the puzzle, different aspects of the puzzle come to life. >> that's very, very -- >> cool. >> my son down there loves when i say lego "star wars," educational, bring them home. that's true of all construction
